Like the sun, the little bulb in this box does not emit the blue spectrum peak present in many artificial light sources that can interfere with a productive night's sleep. Bring the sun inside. Use sun filled LED bulbs anywhere you spend time around your home. Minimize exposure to other blue light sources as you prepare to sleep in the evening. Reducing exposure to blue light spectrum can help you enjoy the kind of sleep dreams are made of. A good night's sleep will help you wake up refreshed and ready for the day. The lightbulb went on when we created our closest light to natural sunlight (sun filled LED bulbs provide 97CRI (color rendering index), minimum R9 80, as compared to natural sunlight at 100CRI). Sun filled LED reduces exposure to blue spectrum, which may help maintain the circadian rhythm, the body's natural sleep-wake cycle - when you sleep well, you feel well, and your best self can fill the day. Use them almost anywhere in place of other bulbs and bask in light closer to sunlight. Lasts 13 years (Based on 3 hours use per day).
